Poor service and no feedback

I ordered mother's day gifts on the woolies online app on the 5th May. I received confirmation that my package will be delivered on the 9th May. Yesterday I called woolworths after receiving no call from couriers and I was informed they not sure why the package is still pending. The consultant informed me that she will escalate the matter but it takes 48 hours for the courier company to respond. How is this my issue? Still no feedback I called again today, same excuse but no one from woolies has been keeping me informed of the situation. Mother's day is tomorrow so I must inform my mom that woolies didn't deliver so her gift is late. Woolies don't prioritize their clients. They now blame the courier company but I purchased the order on woolies website. Poor service from Woolworths.
